I am in FL so I wear rash guards year round to protect myself from the sun. The "Men's Long Sleeve Rash Guard/Cobalt" is a well made item. I really like the design and color- has a sporty look. Fabric, stitching & seams appear to be good quality. Based on the size chart, I went with an large. I am 6'1", 220 lbs with a 34" waist. The fit was better than the red one I purchased. Tight fitting but in the water, it was fine. Sleeve length was good and the hem from the bellybutton down was the proper length. Great rash guard.

Cool looking rashguard I got this rashguard as a gift for my boyfriend and he really loves it! I almost always see him in it when he goes to the gym, which just shows how comfortable it is to wear. He is usually picky when it comes to clothes but this one just fits right to his taste. He told me to buy him more of this and now we're looking forward for more designs!

I love my new rash guard, I paired it with the long pants rash guard, it's perfect it's almost like wearing a full suit but it's just rash guard material which is awesome for the summer and keeps me just warm enough for Southern California beaches running around 66 to 70°F, And these rashcards keep the sun off you add just enough warmth and all the flexibility you could want for surfing.

Happy Rashguard Customer I love this rash guard! I'm 5'8", 161 lbs, 39" in the chest, and the Medium fits well. It's snug but not too tight. The sleeves are long, but that's how I like them. It looks great, and it feels great in the water.

Great product When I received my rash guard, the first thing I noticed was the color. It is bright and vibrant and exactly as pictured. The next thing was the material. It is very soft and comfortable, but it's also extremely durable, which is what you want when you're in the water. The thing I was concerned about was how well it fit and how well it stayed put while swimming and snorkeling. It fit perfectly! It stayed in place even when I got a bit rough with it.

Soft and cosy I love this rash guard! It is super comfortable, and the fabric is very soft. This rash guard is very nice to wear in the water. It is very comfortable, and I like the way it feels against my body! Worth the investment because of the comfort, durability, fit, and style.
